Independent Variable: This is the factor that the researcher intentionally changes. It is the "cause" in a cause-and-effect relationship. In a POGIL activity, you might identify this by looking for the one element that differs between experimental setups.

The control group is a set of test subjects that does not receive the experimental treatment. It provides a standard of comparison. For example, if testing a new fertilizer, the control group would be plants grown without any fertilizer. Without this group, a researcher cannot claim that the independent variable caused the observed change. Designing for Reliability and Validity fundamentals of experimental design pogil

Here’s a structured, “good post” breakdown of — useful for a study group, class discussion, or blog. Independent Variable: This is the factor that the
